실험 절차

Following General Procedure E, N-(4-bromobenzyl)propan-2-amine (200 mg, 0.88 mmol) was reacted with bis(pinacolato)diboron (240 mg, 0.96 mmol) to afford the crude boronic ester which was reacted with 9-bromo-8-methoxythieno[2,3-c]quinolin-4(5H)-one (270 mg, 0.88 mmol) to afford the desired product (190 mg, 57%) as a light brown solid: 1H NMR (500 MHz, CD3CD2OD) δ 7.68-7.63 (m, 2H), 7.56-7.49 (m, 2H), 7.41-7.34 (m, 3H), 6.04 (dd, J=5.4, 2.4 Hz, 1H), 4.33 (s, 2H), 3.72-3.67 (m, 3H), 3.56-3.50 (m, 1H), 1.45 (dd, J=6.6, 2.2 Hz, 6H).
